Jelix-应用程序安装

我使用的是Jelix PHP5框架，当我尝试安装应用程序时，我遇到了以下错误：

php lib/jelix-scripts/jelix -portail installapp
Error: bad path in JELIX_APP_TEMP_PATH, it is equals to '/' !!
   Jelix cannot clear the content of the temp directory.
   Correct the path in JELIX_APP_TEMP_PATH or create the directory you
   indicated into JELIX_APP_TEMP_PATH.

我的portal/application.init.php文件包含：

<?php
/**
 * @licence  http://www.gnu.org/licenses/gpl.html GNU General Public Licence, see LICENCE file
 */
require(dirname(__FILE__).'/../lib/jelix/init.php');
define ('JELIX_APP_PATH', dirname (__FILE__).'/'); // don't change
define ('JELIX_APP_TEMP_PATH',    realpath(JELIX_APP_PATH.'../temp/portail/').'/');
define ('JELIX_APP_VAR_PATH',     JELIX_APP_PATH.'var/');
define ('JELIX_APP_LOG_PATH',     JELIX_APP_PATH.'var/log/');
define ('JELIX_APP_CONFIG_PATH',  JELIX_APP_PATH.'var/config/');
define ('JELIX_APP_WWW_PATH',     realpath(JELIX_APP_PATH.'../www/').'/');
define ('JELIX_APP_CMD_PATH',     JELIX_APP_PATH.'scripts/');

我的portal/application-cli.init.php文件包含：

<?php
/**
 * @licence  http://www.gnu.org/licenses/gpl.html GNU General Public Licence, see LICENCE file
 */
require(dirname(__FILE__).'/../lib/jelix/init.php');
define ('JELIX_APP_PATH', dirname (__FILE__).'/'); // don't change
define ('JELIX_APP_TEMP_PATH',    realpath(JELIX_APP_PATH.'../temp/portail-cli/').'/');
define ('JELIX_APP_VAR_PATH',     JELIX_APP_PATH.'var/');
define ('JELIX_APP_LOG_PATH',     JELIX_APP_PATH.'var/log/');
define ('JELIX_APP_CONFIG_PATH',  JELIX_APP_PATH.'var/config/');
define ('JELIX_APP_WWW_PATH',     realpath(JELIX_APP_PATH.'../www/').'/');
define ('JELIX_APP_CMD_PATH',     JELIX_APP_PATH.'scripts/');

你知道出了什么问题吗？
